The International Space Station orbits around Earth every 92 minutes, carrying a clutch of astronauts along with it. Without earlier space stations, such as the US' Skylab and Russia's Mir, mankind may not have had a permanent station in space.

The film starring Matt Damon and a really, really big space station hits theaters this weekend. Crave's Eric Mack speaks to one of the folks behind humanity's biggest space station about how far off a real-world "Elysium" might be.
